Graduation......

Apple-co-founder Steve Wozniak sent UC Berkeley graduates into the world Saturday with a freewheeling and informal commencement speech -- and two mathematical formulas a fifth-grader could understand:

1) Happiness equals S minus F (smiles minus frowns).

2) Happiness equals F cubed -- food, fun and friends.

I attended this graduation this weekend, and heard a remarkable speech by Steve Wozniak.  He inspired, entertained, and left all of us with smiles on our faces.
